Overwriting erases the display information already displayed on the display screen, and stores the file having the file name selected in the selected file name column 723 among the files stored in the save area of the storage unit 20. The data is read from the save area of the unit 20 and displayed on the display screen.

  In the overwrite confirmation window 725, “OVERWRITE?”, Which is a message for confirming whether or not to overwrite, is displayed, and an “OK” button 726 and an “NG” button 727 are formed. The “OK” button 726 indicates that the overwriting may be performed. When the touch pen 43 is brought into contact with the position of the “OK” button 726, the overwriting is executed. The “NG” button 727 indicates that it should not be overwritten. When the touch pen 43 is brought into contact with the position of the “NG” button 727, the file opening is stopped.

  FIG. 19 is a flowchart illustrating a processing procedure of display processing. When the display device 1 is powered on and ready for operation, the process proceeds to step A1.

  In step A1, the control unit 10 sets the mode of the display device 1 to the pen mode. In step A2, the control unit 10 stores the mode. Specifically, the storage unit 20 stores that the pen mode is set. In step A3, the control unit 10 determines whether or not contact with the touch panel 41 has been detected. Specifically, when the contact detection unit 123 detects that the touch pen 43 has touched the touch panel 41, the control unit 10 determines that contact with the touch panel 41 has been detected, and proceeds to step A4. If the contact detection unit 123 does not detect that the touch pen 43 is in contact with the touch panel 41, it is determined that contact with the touch panel 41 has not been detected, and the process returns to step A3. In step A4, the control unit 10 detects the contact position. Specifically, the control unit 10 receives a position where the touch pen 43 contacts the touch panel 41 from the position detection unit 121.

  In step A5, the control unit 10 determines whether an icon is detected. Specifically, the control unit 10 detects an icon when the position received from the position detection unit 121 is the position of one of the icons of the command control icon group 61 and the scroll icon of the scroll window. It branches to the step of the process corresponding to the icon in the position received from the position detection part 121.

  That is, if the icon at the position received from the position detection unit 121 is the position of the pen icon 611, the control unit 10 proceeds to step A10, and the icon at the position received from the position detection unit 121 is the eraser icon 612. If the position is the position of the line type icon 613, the process proceeds to step A13, and the icon at the position received from the position detection unit 121 proceeds to step A13. Is the position of the color icon 614, the process proceeds to step A14. If the icon at the position received from the position detection unit 121 is the position of the scroll icon 615, the process proceeds to step A15 and is received from the position detection unit 121. The position is one of the scroll cursors 645-648. If it is the position of the cursor, the process proceeds to step A16, and if the position received from the position detection unit 121 is the position of the print icon 616, the process proceeds to step A17, and the position received from the position detection unit 121 is the file icon 617. If it is, the process proceeds to step A18.

  Further, the control unit 10 determines that no icon is detected unless the position received from the position detection unit 121 is the position of any of the icons of the command control icon group 61 and the scroll icon of the scroll window. The process proceeds to step A6.

  In step A6, the control unit 10 determines the mode. Specifically, the control unit 10 reads the mode stored in the storage unit 20. In step A7, the control unit 10 executes a function corresponding to the mode, and returns to step A3. That is, the control part 10 performs the process according to the mode read from the memory | storage part 20, and returns to step A3. Specifically, the control unit 10 performs drawing when the mode read from the storage unit 20 is the pen mode, and executes erasure when the mode read from the storage unit 20 is the eraser mode. When the read mode is the line type mode, the line width is changed. When the read mode is the color mode, the color is changed, and the process returns to Step A3.

  In step A10, the control unit 10 sets the display device 1 to the pen mode. In step A11, the control unit 10 stores the set mode. Specifically, the control unit 10 stores the mode set in steps A10 and A12 to A14 in the storage unit 20. In step A12, the control unit 10 sets the eraser mode and proceeds to step A11. In step A13, the control unit 10 sets the line type mode and proceeds to step A11. In step A14, the control unit 10 sets the color mode and proceeds to step A11.

  In step A15, the control unit 10 executes a scroll area setting process to be described later, and proceeds to step A6. In step A16, the control unit 10 executes a scroll cursor process which will be described later, and proceeds to step A6. In step A17, the control unit 10 executes a printing process described later, and proceeds to step A6. In step A18, the control unit 10 executes file processing to be described later, and proceeds to step A6.

  FIG. 20 is a flowchart showing the processing procedure of the scroll area setting process. When step A15 shown in FIG. 19 is executed, the process proceeds to step B1.

  In step B1, the control unit 10 determines whether or not contact with the touch panel 41 has been detected. Specifically, when the contact detection unit 123 detects that the touch pen 43 is in contact with the touch panel 41, the control unit 10 determines that contact with the touch panel 41 has been detected, and proceeds to step B2. If the contact detection unit 123 does not detect that the touch pen 43 is in contact with the touch panel 41, it is determined that contact with the touch panel 41 has not been detected, and the process proceeds to step B11.

  In step B2, the control unit 10 detects a contact position. Specifically, the control unit 10 receives a position where the touch pen 43 contacts the touch panel 41 from the position detection unit 121. In step B <b> 3, the control unit 10 stores the contact position detection coordinates as start point coordinates as the contact position 27 of the storage unit 20. The contact position detection coordinate here is a coordinate in the XY coordinate system detected as the position where the touch pen 43 is touched in step B2.

  In step B4, the control unit 10 detects the contact position. Specifically, the control unit 10 receives a position where the touch pen 43 contacts the touch panel 41 from the position detection unit 121. In step B5, the control unit 10 performs drag display. Specifically, a drag display that is a rectangular area having the start point coordinates and the coordinates of the position detected in step B4 as diagonal vertices, for example, the drag display 632 shown in FIG. 7 is displayed. In step B6, the control unit 10 determines whether or not the drag has ended. When the contact detection unit 123 detects that the touch pen 43 has moved away from the touch panel 41, the control unit 10 determines that the drag has ended and proceeds to step B7. If the contact detection unit 123 does not detect that the touch pen 43 has moved away from the touch panel 41, it is determined that the drag has not ended, and the process returns to step B4.

  In step B7, the control unit 10 stores the contact position detection coordinates in the storage unit 20 as end point coordinates. The contact position detection coordinates here are the coordinates in the XY coordinate system that were finally detected as the position where the touch pen 43 contacted in step B4. In step B8, the control unit 10 changes the display on the display screen from a drag display determined by the start point coordinates and the end point coordinates to a scroll window display, for example, a scroll window 641 shown in FIG.

  In step B9, the control unit 10 stores the end point coordinates from the start point as the window size. Specifically, the start point coordinate WS (X, Y) and the end point coordinate WE (X, Y) are stored in the start point / end point coordinate storage unit 21. In step B10, the control unit 10 cuts out an image in a range specified by dragging, and ends the scroll area setting process. Specifically, the control unit 10 cuts out information displayed in a rectangular area having the start point coordinates WS (X, Y) and the end point coordinates WE (X, Y) as diagonal vertices. Information is memorize | stored in the memory | storage part 20, and a scroll area setting process is complete | finished. An image is an image and is information representing information to be displayed as a bitmap image.

  In step B11, the control unit 10 determines whether or not a predetermined time has elapsed. When the time measured by the time measuring unit 13 from the input time has elapsed for a predetermined time, for example, 5 seconds, the control unit 10 determines that the predetermined time has elapsed, and ends the scroll area setting process. When the time measured by the time measuring unit 13 from the input time does not elapse for a predetermined time, for example, 5 seconds, it is determined that the predetermined time has not elapsed, and the process returns to Step B1. The input time is the time when the contact position is detected in step B2.

  21 and 22 are flowcharts showing the processing procedure of the scroll cursor processing. When step A16 shown in FIG. 19 is executed, the process proceeds to step C1.

  In step C1, the control unit 10 reads the start point / end point coordinates, substitutes the read start point coordinates WS (X, Y) for the movement start point coordinates IS (X, Y), and reads the end point coordinates WE (X, Y). Is substituted into the movement end point coordinate IE (X, Y). In step C2, the control unit 10 determines which direction the scroll direction is, and branches to a step corresponding to the determined scroll direction. When the scroll cursor at the position touched by the touch pen 43 is the upward scroll cursor 645, the control unit 10 proceeds to Step C3. When the scroll cursor at the position touched by the touch pen 43 is the downward scroll cursor 646, the process proceeds to step C3. When the scroll cursor at the position touched by the touch pen 43 is the right scroll cursor 647, the process proceeds to step C3. When the scroll cursor at the position touched by the touch pen 43 is the left scroll cursor 648, the process proceeds to step C3.

  FIG. 23 is a diagram for explaining the start point coordinates and the end point coordinates after the image is moved. The area 91 is a rectangular area having the start point coordinates WS (X, Y) designated by the touch pen 43 and the end point coordinates WE (X, Y) designated by the touch pen 43 as diagonal vertices. This is an area of the formed scroll window.

FIG. 24A shows an example in which the image displayed in the scroll window is moved in the direction of arrow A, that is, in the lower right direction. A blank area 93a is formed in a portion of the scroll window area 91 excluding the moved image area 92a. In this case, the movement amount in the X-axis direction is “−X”, and the movement amount in the Y-axis direction is “−Y”.

  FIG. 24B shows an example in which the image displayed in the scroll window is moved in the direction of arrow B, that is, in the upper left direction. A blank area 93b is formed in a portion of the scroll window area 91 excluding the moved image area 92b. In this case, the movement amount in the X-axis direction is “+ X”, and the movement amount in the Y-axis direction is “+ Y”. Characters, figures, and the like can be entered with the touch pen 43 in the blank areas 93a and 93b.

  Referring to FIG. 21, in step C3, control unit 10 moves the image of the end point coordinates from the start point to the lower side of the screen. That is, the image displayed in the rectangular area having the start point coordinates and the end point coordinates as diagonal vertices is moved downward in the display screen. In step C4, the control unit 10 updates the movement start point coordinates IS (X, Y) and the movement end point coordinates IE (X, Y) to the coordinates after movement. In step C5, the control unit 10 reads the start point coordinates WS (X, Y) and the end point coordinates WE (X, Y) from the start point / end point coordinate storage unit 21.

  In step C6, when the X coordinate of the start point of the scroll window is equal to or less than the X coordinate of the start point after the movement, and the Y coordinate of the start point of the scroll window is equal to or less than the Y coordinate of the start point after the movement, Proceed to C10. If the X coordinate of the start point of the scroll window is not less than or equal to the X coordinate of the start point after movement, or the Y coordinate of the start point of the scroll window is not less than or equal to the Y coordinate of the start point after movement, the process proceeds to step C20.

  In step C7, the control unit 10 moves the image of the end point coordinates from the start point in the upward direction on the screen. That is, the image displayed in the rectangular area having the start point coordinates and the end point coordinates as diagonal vertices is moved upward in the display screen, and the process proceeds to Step C4. In step C8, the control unit 10 moves the image of the end point coordinates from the start point to the left side of the screen. That is, the image displayed in the rectangular area having the start point coordinates and the end point coordinates as diagonal vertices is moved leftward on the display screen, and the process proceeds to step C4. In step C9, the control unit 10 moves the image of the end point coordinates from the start point to the right side of the screen. That is, the image displayed in the rectangular area having the start point coordinates and the end point coordinates as diagonal vertices is moved to the right of the display screen, and the process proceeds to step C4.

  In step C10, the control unit 10 scrolls when the X coordinate of the end point of the scroll window is equal to or greater than the X coordinate of the end point after movement, and the Y coordinate of the end point of the scroll window is equal to or greater than the Y coordinate of the end point after movement. Ends cursor processing. If the X coordinate of the end point of the scroll window is not equal to or greater than the X coordinate of the end point after movement, or the Y coordinate of the end point of the scroll window is not equal to or greater than the Y coordinate of the end point after movement, the process proceeds to step C20.

  In Step C20, the control unit 10 calculates the (X, Y) movement amount from the start point coordinates and the moved start point coordinates. In step C <b> 21, the control unit 10 stores the calculated (X, Y) movement amount, that is, the movement amount of the X coordinate and the movement amount of the Y coordinate in the storage unit 20.

  In Step C22, the control unit 10 adds a new drawing area (hereinafter referred to as “margin area”) in the scroll window from the movement amount of the X coordinate and the movement amount of the Y coordinate. When the coordinates are (−X, Y), a blank area is added on the left side of the cut image. When the movement amount coordinate representing the movement amount is (+ X, Y), a blank area is added on the right side of the cut-out image. When the movement amount coordinate is (X, -Y), a blank area is added above the cut image. When the movement amount coordinate is (X, + Y), a blank area is added below the cut-out image. When the movement amount coordinates are (−X, −Y), blank areas are added on the left side and the upper side of the cut-out image. When the movement amount coordinates are (+ X, + Y), blank areas are added on the right side and the lower side of the cut-out image.

  The movement amount coordinate represents the relative positional relationship of the position before the movement starting from the position after the movement, and “−X” represents that the image has moved in the positive direction of the X axis direction, that is, the right direction. , “X” represents that the image has not moved in the X-axis direction, “+ X” represents that the image has moved in the negative direction of the X-axis direction, that is, leftward, and “−Y” represents “Y” indicates that the image has moved in the positive direction of the Y-axis direction, that is, upward, “Y” indicates that the image has not moved in the Y-axis direction, and “+ Y” indicates that the image is negative in the Y-axis direction. This means that it has moved in the direction, that is, downward.

  In step C23, the control unit 10 determines whether or not the X coordinate of the movement amount is “−X”. When the X coordinate of the movement amount is “−X”, the process proceeds to Step C27, and when the X coordinate of the movement amount is not “−X”, the process proceeds to Step C24. In Step C24, the control unit 10 determines whether or not the Y coordinate of the movement amount is “−Y”. When the Y coordinate of the movement amount is “−Y”, the process proceeds to Step C29, and when the Y coordinate of the movement amount is not “−Y”, the process proceeds to Step C25. In Step C25, the control unit 10 determines whether or not the X coordinate of the movement amount is “+ X”. When the X coordinate of the movement amount is “+ X”, the process proceeds to step C31, and when the X coordinate of the movement amount is not “+ X”, the process proceeds to step C26. In step C <b> 26, the control unit 10 determines whether or not the Y coordinate of the movement amount is “+ Y”. When the X coordinate of the movement amount becomes “+ Y”, the process proceeds to step C33, and when the Y coordinate of the movement amount does not become “+ Y”, the scroll cursor processing is ended.

  In Step C27, the control unit 10 sets the start point coordinates before the movement as new start point coordinates as they are for the movement start point coordinates IS (X, Y). In step C28, the control unit 10 sets the end point coordinate after movement as a new end point coordinate for the movement end point coordinate IE (X, Y), and proceeds to step C24. In step C29, the control unit 10 sets the start point coordinates before the movement as new start point coordinates as they are for the movement start point coordinates IS (X, Y). In step C30, the control unit 10 sets the end point coordinate after movement as a new end point coordinate for the movement end point coordinate IE (X, Y), and proceeds to step C25. In Step C31, the control unit 10 sets the new start point coordinates after the movement for the movement start point coordinates IS (X, Y). In step C32, the control unit 10 sets the end point coordinate before the movement as the new end point coordinate as it is for the movement end point coordinate IE (X, Y), and proceeds to step C26. In Step C33, the control unit 10 sets the moved start point coordinates IS (X, Y) as the new start point coordinates.

That is, the control unit 10 reads the image of the scroll unit from the save area of the storage unit 20 and stores it in the in-scroll image storage unit 24.

  In step E20, the control unit 10 determines whether or not contact with the touch panel 41 has been detected. Specifically, when the contact detection unit 123 detects that the touch pen 43 is in contact with the touch panel 41, the control unit 10 determines that contact with the touch panel 41 has been detected, and proceeds to step E21. If the contact detection unit 123 does not detect that the touch pen 43 is in contact with the touch panel 41, the control unit 10 determines that contact with the touch panel 41 has not been detected, and returns to step E20. In step E21, the control unit 10 detects a contact position. Specifically, the control unit 10 receives a position where the touch pen 43 contacts the touch panel 41 from the position detection unit 121.

  In step E22, the control unit 10 executes the open and ends the file processing. That is, when the position received from the position detection unit 121 is the position of the OPEN button 724 of the OPEN file designation window 721, the control unit 10 displays the entire image excluding the scroll unit stored in the non-scroll image storage unit 23. The scroll window is displayed in a rectangular area with the start point coordinates WS (X, Y) and the end point coordinates WE (X, Y) stored in the scroll coordinate storage unit 22 as diagonal vertices. , The scroll image stored in the scroll image storage unit 24 is displayed in the scroll window, and the file processing is terminated.

  Thus, the display unit 40 has a display screen and displays information on the display screen. The touch pen 43 designates a rectangular area within the display area of the display screen. And the control part 10 maintained the display state of the information outside a rectangular area currently displayed in the remaining area except the rectangular area designated with the touch pen 43 among the display areas of a display screen, ie, the display state of the whole image except a scroll part. The rectangular area information displayed in the rectangular area designated by the touch pen 43, that is, the image of the scroll part is displayed on the display unit 40 so as to be scrollable in the rectangular area. Therefore, a new display area can be secured at an arbitrary position in the display screen.

  Further, the scroll cursor scrolls the information in the rectangular area within the rectangular area. The touch pen 43 inputs information in the rectangular area. When the scroll cursor scrolls the information in the rectangular area, the control unit 10 forms a blank part in the rectangular area. When the blank part is formed, information is input when the touch pen 43 is input. Information is displayed in the blank area. Therefore, characters and the like can be entered in the newly secured display area.

  Further, when the file output unit 26 prints the information displayed on the display screen, the control unit 10 uses the rectangular area information and the information input to the blank portion by the touch pen 43 as the rectangular area. Separated from external information, the file output unit 26 prints the information. Therefore, since the information in the rectangular area is printed separately, the characters and the like are reduced so that it is not difficult to see.

  Further, when the control unit 10 causes the file output unit 26 to print the information outside the rectangular area, the information within the rectangular area and the information input to the blank portion by the touch pen 43 are separated from the information outside the rectangular area. The file output unit 26 is controlled so that printing is performed in addition to the information outside the rectangular area. Therefore, since it is clearly shown that they are separated and printed, it is possible to prevent misunderstanding that they are displayed in the rectangular area.

  Further, when the file output unit 26 prints the information displayed on the display screen, the control unit 10 uses the rectangular area information and the information input to the blank portion by the touch pen 43 as the rectangular area. The file output unit 26 is controlled so that the information is reduced to a size that fits within the area, and the reduced information is printed in the rectangular area. Therefore, the information in the rectangular area is also printed on the same page as the information outside the rectangular area, so that the positional relationship with the information outside the rectangular area can be easily understood.

  Further, when the file output unit 26 prints the information displayed on the display screen, the touch pen 43 uses the information in the rectangular area and the information input to the blank portion by the touch pen 43 as the information outside the rectangular area. Selects whether to display separately or within the rectangular area. When the control unit 10 selects to display the information outside the rectangular area separately from the information outside the rectangular area by the touch pen 43, the control unit 10 receives the information in the rectangular area and the information input to the blank portion by the touch pen 43, as described above. When printing is performed separately from the information outside the rectangular area and displayed within the rectangular area by the touch pen 43, the information within the rectangular area and the information input to the blank portion by the touch pen 43 are The file output unit 26 is controlled so as to reduce the size to fit within the rectangular area and print the reduced information in the rectangular area. Accordingly, it is possible to select whether to print separately or within the rectangular area in consideration of the relationship between the character size and information outside the rectangular area.
